Title: Optical recording/reproducing device
Inventor: TAKEUCHI RYOJI
IPC: G11B19/04
Filed: 1993-12-29
Abstract: PURPOSE:To surely prevent overlapped writing by preventing erroneous detection and omission in detection without judging recording in a detect area on an optical information recording medium as overlapped writing. CONSTITUTION:An optical disk is irradiated with a laser beam modulated by a recording signal. The reflected optical beam thereof is detected by a detector 12 and binarized with a certain threshold level as a reference. The binarized signal is compared with the recording signal, and when both are not matched a detecting signal from a detecting circuit 30 is generated so as to define that this record is for recording in a recording area or in a defect area. This detecting signal is counted by a counter circuit 31, and when no detecting signal is generated continuously a specified number of times, an optical recording operation is executed as defect detection and the counted value of the detecting signal is cleared. Conversely, when detecting signals are continuously detected and the number of these reaches a specified value, by judging that these are recording in the recording area a signal for prohibiting recording thereof is outputted from the counter circuit 31.
